Belite-Rich Cement - A more Environmentally Friendly Alternative to Ordinary Portland Cement

Abstract:

Today, the attention of many research teams in various industries is focused on reducing greenhouse gas emissions, especially reducing carbon dioxide production. Ordinary Portland cement (OPC) regarding the scale of its production around the world (annual production is around 3 Gt) is a major contributor to the carbon dioxide produced. Approximately one ton of CO₂ is formed per ton of Portland clinker. Thanks to this, there is a general effort to find a suitable alternative that would partially or even fully replace the OPC. One of the possible alternatives is to burn the clinker to a lower temperature (1 250 – 1 300 °C) and thus obtain clinker where the majority phase will be belite instead of alite. Belite-rich clinker is currently used for types of cement with low heat of hydration and good durability properties. For this reason, there is a growing interest in this non-traditional cement. In this study, several points concerning belite-rich clinker production were examined: (i) the optimal C/S ratio to result in belite, (ii) the optimum firing temperature, and (iii) the potential impact of the temperature shift on the composition.
